2 Claims.

This invention relates generally to logging, and particularly to a lineclamp.

The main object of this invention is to construct a clamp whereby a linemay be fastened to a stump or tree without the use of spikes such as arecommonly employed for that purpose when a guy line is fastened to thestump.

The second object is to so construct the clamp that it willautomatically take up the grip on the hauling line.

The third object is to so construct the clamp that its elements will lieclose to the periphery of the stump or tree.

The fourth object is to make the action of the wedging member reversibleunder tightening or loosening conditions of the line.

I accomplish these and other objects in the manner set forth in thefollowing specification as illustrated in the accompanying drawing, inwhich:

Fig. 1 is a plan showing the device attached to a stump.

Fig. 2 is a section taken along the line 22 in Fig. 1.

Fig. 3 is a section taken along the line 3- in Fig. l.

Fig. 4 is a side elevation of the device separated from the line.

Fig. 5 is a perspective View of the ferruled rope section.

Fig. 6 is a fragmentary view showing the interior of the rope engagingjaws.

Similar numerals refer to throughout the several views.

Referring in detail to the drawing, there is shown a back plate ithaving the converging sides I I and 2, the side i 1 having the flange itformed thereon and the side similar parts toggle lever 23, it is held toeither of the hooked,

projections 24 or 25, thereby enabling the spring 2| to urge the wedgeiii in either direction as desired.

It is desirable to provide a socket 26 at one end of the side I! toreceive the ferrule 2'! of the short cable 28 Whose other ferrule 29 isl2 having the grooved face it formed thereon adapted to 0011-.

seated in the eye 30 through which the cable l5 passes after it hasencircled the stump 3!. The end 32 of the cable I5 is attached to a spartree or other object to be fastened while the end 33 of the cab-1e I5 isattached to the cable winding drum, not shown.

A hook 34 is formed on the side l2 for the purpose of holding the clampagainst the stump under conditions when the line portions areapproximately parallel in which case the hauling action would tend todraw the clamp away from the stump. In use the'hook 3G is simply used tohold a small line which encircles the stump 3|. It is desirable toprovide the ears 3? on the side I 2 to hold the Wedge it in position;

The operation of the device is as follows:

The end 32 of the cable i5 is passed around the stump 3i through the eye38 to a point of fastening on the spar tree. The clamp plate NJ is thenput into position on the cable l 5 between the stump 3i and the end 33of the cable iii. The short cable 28 which projects from the eye 30 isthen attached to the socket 26 of the member Ill. A pull from thewinding mechanism is then applied to the end 33 which causes the memberI!) to move toward the stump 3! if the line portions 32 and 33 divergeas shown in Fig. 1. If they do not diverge, however, it is desirable tosecure the member Ill tothe stump 3| by means of a lashing passed aroundthe stump 3i and'secured to the hook 34. As the pull is exerted on thecable 55, the wedge IS under the urging of the spring 2i takes up theslack so that whenever the pull ceases, the cable l5 issecurely grippedbetween the Wedge l6 and the clamp side l2.

When releasing the clamp, it is first necessary to reverse the pull ofthe spring 2! and then place a strainon the cable end 33 therebyimmediately freeing the cable from the grasping action of the device.

Obviously, any other form of means for holding the eye 30 toward themember it may be utilized without departing from the spirit o-fithisinvention.

I claim:

, l. A line clamp having in combination a channel shaped member thesides of which converge, a wedge disposed within said channel adapted tohold a line between same and an adjacent side of said channel, a, springadapted to selectively urge said wedge toward or away from a wedgingposition and an eye attached to one side of said body through which aline may pass after it is passed through said clamp and around a stumpfor the purpose of holding said clamp toward said tached to one side ofsaid body through which stump. a line may pass from a spar tree to astump and 2. A line clamp having in combination an elonthence betweenthe wedge of said clamp and an gated channel shaped body, the sides ofwhich adjacent side of the channel, said wedge having 5 converge, awedge disposed between said cona reversible spring element adapted toselective- 5 verging sides, means for securing the converging 1y urgesaid wedge in either direction. end of said body against a stump and aneye at- WILLIAM L.
